Sorghastrum nutans #2 (Indian Grass)

Indian Grass is one of the “Big Four” dominant grasses of the tallgrass prairie ecosystem. It has amazingly deep roots which results in excellent drought tolerance and its ability to grow in poor, lean soils in full sun. Once it flowers, it has a tendency to flop if it is in too much shade. The greenish-blue foliage grows to about 3′ tall while the feathery flower plumes extend far above it at 6′ tall in August. The clumping, upright habit of Indian Grass makes for an excellent native substitute for the invasive, non-native Miscanthus grass.

The strong, bright yellow flower stalks remain erect throughout the fall and winter, making it a very attractive architectural element during the dreary months. Many granivorous birds eat the seeds and many insectivorous birds are attracted to the other insect life that rely on this plant. Its strong presence throughout winter makes for great cover and a good supply of nesting material. The Pepper and Salt Skipper uses this plant as a larval host.
